What compiler version are you using? Does the behaviour change if you
use a newer/older compiler? It sounds to me like there's some deeper bug
and your patch is just papering over it.

I tried with gcc 4.3.2. Let me try with a recent version and update.

Agreed, this doesn't make any sense. Try changing the compiler version to see if
the problem goes away or stops.  It might also be worthwhile to dump the
contents of the device tree at the start and end of the kexec process.  If the
changing of how a function is inlined is causing a hang, its likely changing how
the putprops function is writing information to the device tree.  Understanding
what that change is will likely provide clues to how the code has changed.

Neil, there was no code change in fs2dt.c
